  摘要：

  已经进行了环取代对1，1-二芳基烷氧基自由基反应性影响的产物和时间分辨动力学研究。所述基团经历O-新叶酸移位，以给出异构的1-芳基-1-芳氧基烷基，从其形成相应的芳族酮。重排速率常数受环取代的影响，在吸电子取代基的存在下增加，而在供电子取代基的存在下降低。根据产物和动力学研究的结果，获得了以下迁移能力：4-三氟甲基苯基>苯基≅4-甲基苯基> 4-甲氧基苯基。σ +之间的出色Hammett型相关性获得了取代基常数以及可见吸收带最大值和重排速率常数。实验结果表明，重排受起始的1,1-二芳基烷氧基自由基的电子效应支配，而重排的以碳为中心的自由基的稳定性起次要作用，与类似反应物的过渡态一致，强烈支持了1，1-二芳基烷氧基基团的O-新叶重排通过协调机制进行的假说。

  摘要：

  三氟甲基芳烃的药物重要性的提高刺激了更有效的三氟甲基化反应的发展。大量努力集中于铜和钯介导的/催化的芳基卤化物的三氟甲基化。相反，不存在将广泛使用的惰性亲电子试剂如苯酚衍生物转化为相应的三氟甲基化芳烃的通用方法。本文报道的是苯酚衍生物与容易获得的三甲基（三氟甲基）硅烷（TMSCF 3）进行的镍介导的三氟甲基化反应。该策略依赖于PMe 3促进的氧化加成和过渡金属化以及CCl 3CN诱导的还原消除。通过将三氟甲基直接掺入芳族和杂芳族体系（包括生物相关化合物）中，已证明了这种转化的广泛用途。

• Suzuki–Miyaura Cross-Coupling of <i>N</i>-Acylpyrroles and Pyrazoles: Planar, Electronically Activated Amides in Catalytic N–C Cleavage
  作者：Guangrong Meng、Roman Szostak、Michal Szostak

  日期：2017.7.7

  The formation of C–C bonds from amides by catalytic activation of the amide bond has been thus far possible by steric distortion. Herein, we report the first example of a general Pd-catalyzed Suzuki–Miyaura cross-coupling of planar amides enabled by the combination of (i) electronic-activation of the amide nitrogen in N-acylpyrroles and pyrazoles and (ii) the use of a versatile Pd-NHC catalysis platform

  迄今为止，由于空间扭曲，通过酰胺键的催化活化作用由酰胺形成C–C键是可能的。本文中，我们报道了一般的Pd催化的Suzuki-Miyaura平面酰胺交叉偶联的第一个例子，该偶联可通过以下方式组合实现：（i）电子活化N-酰基吡咯和吡唑中的酰胺氮，以及（ii）使用多功能的Pd-NHC催化平台。讨论了形成酰基金属的起源和选择性，包​​括扭曲的作用。

  the first amide cross-coupling by direct metal insertion of simple and readily available primary amides. The overall strategy by N,N-di-Boc activation/metal insertion is suitable for a broad range of coupling protocols via acylmetals. Mechanistic experiments suggest high reactivity of N,N-di-Boc activated 1° amides in direct amide C–N cross-couplings.
